求求大神告诉我哪儿错误了。

#include<stdio.h>

#define N   10

void S(int score[])

{  int total,max,min,i,j;double ping;

    for( i=0;i<10;i++)

{

     total+=score[i];

  if(max<score[i])   max=score[i];

  if(min>score[i])   min=score[i];

}ping=total/10;

printf("最高分：%d\n",total);

printf("平均分：%.2f\n",ping);

printf("最高分：%d\n",max);

printf("最低分：%d\n",min);

printf("成绩降序排列：\n");

for(i=9;i>=0;i--)

for(j=0;j<i;j++)

{

   if(score[j]<score[j+1])

   {

      score[j]=score[j]+score[j+1];

 score[j+1]=score[j]-score[j+1];

 score[j]=score[j]-score[j+1];

   }

}for(i=0;i<10;i++)

if(i==9)

printf("%3d",score[i]);

else  printf("%3d,",score[i]);

}

void mian()

{

int A[N]={1,2,3,4,5,6,7,8,9,10};

S(A);getchar();

}
